default LongStream.Builder add(long t)
Parameters: This method accepts a mandatory parameter t which is the element to input into the stream.
Exceptions: This method throws IllegalStateException when the builder has already transitioned to the built state. It means that the stream has entered the built phase and now no it can’t be changed. Hence no more elements can be added into the stream.

Example 2: To illustrate IllegalStateException
Stream successfully built 4 5 6 7 Exception thrown when now adding element into the stream: java.lang.IllegalStateException
